Well, joking aside......and an honkin' big guffaw is the best way of dealing with nitwittery like this......what you're looking at with this perfect health diet site is a marketing ruse to drive the sales of a crack-pot diet book. A very common ploy on the Internet these days (witness all the blogs for Vibram minimalist shoes and barefoot running etc.) It's called "organic" marketing.

This is the home of that >>70%Fat/Strange Carb diet, remember......and the authors are relying on the general lack of appropriate scientific knowledge/critical thinking skills/gullibility of their audience when writing about the stuff they do in the way they do.
